Certain embodiments are directed to control methods, window controllers, and uninterruptible power supplies for determining tinting instructions for optically switchable windows to reduce power usage at a site during a reduced power event. In some cases, reduced power operations are initated by a window controller upon receipt of a trigger signal from an uninterruptible power supply sent when it detects a power loss. In some cases, tinting instructions are based on the remaining charge left on the uninterruptible power supply. In some cases, reduced power operations are delayed for a period of time.

The invention provides an elastomeric optical device having a first optical state and a second optical state. The device is transparent when in the first optical state and translucent or opaque when in the second optical state. The device comprises, in sequence, a first transparent electrode, a dielectric layer, an elastomer layer, and a second transparent electrode. The elastomer layer preferably has certain mechanical properties, such as a Shore OOO hardness of less than 15, and/or certain chemical properties, such as being substantially devoid of unreacted sites. The second transparent electrode is configured to compress the elastomer layer in response to an electric field between the first and second transparent electrodes, such that when the elastomeric optical device is in the second optical state, the elastomer layer is compressed between the first and second transparent electrodes. Methods of operating an elastomeric optical device are also provided.
